LEWlER-CONTRULLING DEVICE "EUR FLlNElAlLbllEl-llt .llUJEMBILE To all fwwm 'it may concern .lle it known that l, Barron D. Srnvnnson, a citizen of the United States, residing at lilarvard, in the county of McHenry and State of illinois, have invented a new and useful improvement in Lever-Controlling Devices for `ljlanetary-Groar Automobiles, of which the following is a specificationu lvly invention relates to certain new and useful improvements in lever-controlling devices foil planetary gear automobiles and is fully described and explained in the speer lication and shown in the accompanying drawings, in wl1ichlfigure l is a side elevation showing my device attached to the transmission "of a .Ford car and Fig. 2 is a plan of my device and certain adjacent parts.

Referring to the drawings, 3 is the clutch pedal, d the clutch lever, 5 the slow-speed connection and clevis, and 6 is the cam car ried by the controller shaft. l of known form. rl`he arrangement is such that when the pedal 3 is pushed forward the low speed gears come into action, when it is in mid position the gears are in neutral and when released the clutch engages for direct driving. rl`he parts may be held in neutral by the cam G controlled by the emergency brake L lever (not shown), EB is the reverse pedal.

ln installing my device the clutch lever screw is removed and replaced by a longer screw 9, the upper end of which is bifurcated, the furcations being connected by a pin l0. ll is a hoolr of adjustable length, pivoted to the forward end of the slow speed connection. 'lhis connection may conveniently be made by replacing the stoclr slow-speed connection with one havingla t ie perforate end of the hook l1 may be slipped into place and held with a cotter pin. The rear end of the hook lies between the fnrca tions of the screw 9 and, when the gears are in neutral, the hooked end lies just to the rear of the pin lO. A spring l2 con nects the hook with the reverse pedal, its

length being such that when the pedal is in normal or rear positions there is no tension on the spring, but, on the contrary, the turns of the spring are in close contact so that the rear end of the hoolr is pressed quite definitely, but lightly down.

'lfhe operation is as follows: Starting with the gears held in neutral, either by the foot or by the controller shaft, the reverse pedal Specification ot' Letters Patent.

is pressed forward enough to raise the rear end of the hoolr so astobe in position to engage the pin l0. rllhe clutch pedal is then set free (either by removing the foot from` on the clutch pedal to return it to normal.`

or rear position. itllpedals may then be released and the gears will stay in neutral, or the car may be backed at will without danger of having either the clutch or sloww speed band in partial engagement. However, the reverse pedal being released and the clutch pedal moved forward for slow speed, the hoolr will immediately be released from the pin and the car may/be run forward in low gear. lifter this, if the reverse pedal be not again pressed, the clutch pedal may be released without interferenceby the hook, for the rear end of the hoolr lies in the bottom of the slot in the pin 9, except when raised by the reverse lever or held up after such rising movement. @n the other hand, if several movements, first forward and then bach, must be performed as in turning, the hoolr will engage and prevent the clutch from going in, providing only that the reverse pedal be pushed forward slightly before or as the clutch pedal moves back to neutral position.

llhus the attachment interlocls the reverse and clutch pedals so that when the reverse pedal is in action in the normal way the gears are held accurately in neutral, and yet no normal or proper action of the pedals is remotely interfered with. llt not only pre vents dragging of the clutch or slow-speed band in reversing with the emergency brake lever pushed down, but, under like conditions, frees one foot so that the reverse pedal and foot brake can be operated in rapid suecession without shifting the foot from one pedal to the other as is usually required.

l realize that considerable variation is possible in the details of the construction herein shown, and l do not intend to limit myself thereto, except as pointed out in the following claims, in which it is my intention to claim all the novelty inherent in the device as broadly as is permitted by the state of the prior art.

I claim: 4

1. The combinaticmmwithA a i planetary transmission having a rClutch pedal which in forward position sets the slow speed band and in rear position sets the clutch, and a reverse pedal, of meansset by the reverse pedal and released by movement of the clutch pedal to slow speed position for locking the clutch pedal against movement to high speed position.

2. The combinationA with a planetary transmission having va clutch pedal which in forward position sets the slow speed band and in rear position sets the clutch and a reverse pedal, of a hook device carried by the clutch pedal and connected with the reverse pedal and arranged, as the reverse pedal is moved',v to lock the clutch pedal against movement to high speed position and to be released by the movement of the clutch pedal to low speed position.

3. The combination with a planetary transmission having a clutch pedal which infn forward position sets the slow speed band, a clutch lever link connected with the clutch pedal to permit thc clutch to engage upon rear movement olf the clutch pedal, a reverse pedal, ot' a locking device pivoted to the clutch pedal and connected to the reverse pedal to he operated upon the morement thereof to engage with the (,'lnteh lever to prevent the movement ot the clutch pedal to high speed position, and adapted to release upon movement oit the clutch pedal to slow speed. position.

at. The herein described attachment coinprising a slotted bolt adapted to replawx the clutch lever adjusting screw, a hook adapted to be pivoted te Ithe elntrh pedal at its .lower end and to lie within the slot oi' said bolt and a spring eonnectible with the reverse pedal to raise the hook into engaging posi`4 tion upon the operation et the reverse pedal.

In testimony whereof l have hereunto set my hand this 9th day of August. i917.
